Description

Multi-card terminal paging conflict coordination method based on shared base station

technical field

The present disclosure generally relates to the technical field of wireless communication, and more particularly, to the technical field of 5G communication.

Background technique

Detailed ways

The following detailed description is made with reference to the accompanying drawings and is provided to assist in a comprehensive understanding of various example embodiments of the present disclosure. The following description includes various details to aid in understanding, but these details are to be regarded as examples only, and not for the purpose of limiting the disclosure, which is defined by the appended claims and their equivalents.

Those of ordinary skill in the art will recognize that various changes and modifications of the examples described herein can be made without departing from the spirit and scope of the present disclosure.

Figure 1 schematically illustrates a schematic diagram of a Multi-Operator Core Network (MOCN) architecture. Under the multi-operator core network (MOCN) architecture, as shown in Figure 1, multiple mobile communication operators (such as China Telecom, China Mobile and/or China Unicom) can co-build and share communication base stations and communication cells/frequency points , and then build up respective communication core networks on this basis, such as the core network of operator 1 and the core network of operator 2 shown in FIG. 1 .

The present invention proposes a multi-card terminal paging conflict coordination mechanism based on a co-construction and sharing scenario, wherein, in the case of a paging conflict, the paging conflict is avoided through the coordination processing of the shared base station.

FIG. 2 schematically illustrates a flow chart of a method for coordinating paging conflicts for dual-card terminals based on a shared base station according to the present invention. Correspondingly, FIG. 3 schematically illustrates the signaling flow of the paging occasion (PO) coordination configuration mechanism in the shared base station-based dual-card terminal paging conflict coordination method according to the present invention.

In step S201, the multi-card terminal (eg, dual-card terminal) reports information about the mobile network to which each SIM card of the terminal is connected to the shared base station. Correspondingly, the shared base station receives the information reported by the multi-card terminal about the mobile network accessed by each SIM card of the multi-card terminal. The information about the mobile network accessed by each SIM card may include, for example: whether the terminal is a dual-card terminal; and which operator network each SIM card in the terminal accesses. The operator network is also known as the Public Land Mobile Network (PLMN). A shared base station is a base station shared by multiple operators under the multi-operator core network (MOCN) architecture. Often, shared base stations are also jointly built by multiple operators. This step is shown in Figure 3 as the topmost signaling from the dual SIM terminal to the shared base station.

Then, in step S202, the shared base station determines whether there is a conflict in the paging occasions (PO) of each SIM card corresponding to the multi-card terminal.

When the paging parameter Ns>=2, each paging radio frame contains more than one paging occasion (PO).

As a preferred example, a paging occasion (PO) corresponds to a subframe in a paging frame (PF), and different paging occasions (PO) correspond to different subframes in a paging frame (PF).

For example, the paging occasions (PO) of the two SIM cards of the dual-card terminal are the same, and the paging occasions (PO) of the two SIM cards of the dual-card terminal correspond to the same subframe in the paging frame (PF), then the shared The base station determines that the paging occasion (PO) of each SIM card corresponding to the dual-card terminal is in conflict.

In the case that the shared base station determines that the paging occasions (PO) of the respective SIM cards corresponding to the dual-card terminal are in conflict, the following processing is performed to solve the problem of the paging conflict of the dual-card terminal.

Specifically, for example, in step S203, the shared base station allocates different paging occasions (PO) to each SIM card of the dual-card terminal. For example, the PO coordination configuration mechanism on the network side is used to solve the paging conflict problem, and the PO coordination configuration signaling is indicated to the dual-card terminal. For example, the conflicting PO may be allocated to one of the SIMs for use, while the PO adjustment is performed on the SIM card that has not been allocated the conflicting PO, and the other PO is allocated to the SIM card that has not been allocated the conflicting PO. Such a process is exemplified in FIG. 3 as a process of "base station finds paging conflict and performs paging conflict coordination". As a preferred example, when the shared base station allocates different paging occasions (POs) to each SIM card of a multi-card terminal (for example, a dual-card terminal), the conflicting paging occasions (POs) can be allocated to one SIM card, and Additional different paging occasions (POs) are allocated for other SIM cards.

In step S204, the shared base station delivers the paging occasion (PO) configuration information to the dual-card terminal. Such steps are illustrated in Figure 3 as intermediate signaling from the shared base station to the dual SIM terminal.

Further in step S205, after receiving the paging occasion (PO) configuration information, the dual-card terminal completes the configuration and feeds back to the shared base station that the configuration has been completed. Accordingly, the shared base station receives feedback of the completed configuration from the multi-card terminal that has completed the configuration. Such a process is exemplified in FIG. 3 as the process of "UE receives PO coordination configuration signaling and receives call in configured PO subframe" and the bottommost signaling from dual-SIM terminal to shared base station. After the configuration is completed, each SIM card of the multi-card terminal receives calls at different assigned paging occasion (PO) subframes, and can avoid paging conflicts.

If the shared base station determines that there is no conflict between the paging occasions (PO) of the respective SIM cards corresponding to the dual-card terminal, the process ends directly. For example, the paging occasions (PO) of the two SIM cards of the dual-card terminal are different, for example, the paging occasions (PO) of the two SIM cards of the dual-card terminal correspond to different subframes in the paging frame (PF), Then, the shared base station determines that there is no conflict between the paging occasions (PO) of each SIM card corresponding to the dual-card terminal.

The following is a specific example to describe how the paging occasions (PO) of each SIM card corresponding to the multi-card terminal collide and how to perform paging conflict coordination.

FIG. 4 schematically illustrates a situation where the paging occasions (PO) of two SIM cards of the dual-card terminal collide and the manner of coordinating the conflict of paging occasions (PO) of the two SIM cards of the dual-card terminal.

As shown in FIG. 4 , a paging frame (PF) is included in the DRX (discontinuous reception) cycle of the current device, and a subframe corresponding to a paging occasion (PO) is included in the paging frame (PF).

For example, SIM card 1 is China Telecom, and SIM card 2 is China Unicom. The co-construction and sharing base station found that the paging conflict problem occurred in subframe 5, and decided to allocate subframe 5 to the China Telecom SIM card, and select subframe 8 from other configurable POs as the paging monitoring subframe of China Unicom card.

FIG. 5 schematically illustrates a schematic diagram of resolving paging occasion (PO) conflicts of two SIM cards of a dual-card terminal.

As shown in FIG. 5 , the dual-card terminal and the shared base station resolve the paging occasion (PO) conflict between the two SIM cards of the dual-card terminal through steps 1 to 4 shown in the figure, so that the PO selection subframe 5 is finally allocated. For the China Telecom SIM card, the PO selection subframe 8 is allocated to the China Unicom SIM card, thereby successfully resolving the paging occasion (PO) conflict.

The present invention creatively utilizes the condition of network co-construction and sharing, and advantageously solves the problem of paging conflict of multi-card terminals through coordination processing between networks. More specifically, the present invention introduces the specific design of multi-card terminal capability reporting and signaling. The present invention enables the network side to actively discover the paging conflict problem, and the present invention designs a shared base station paging occasion (PO) coordination process to solve the problem.
